Product Description
The XM-15B Universal Bluetooth Serial Module is a high-performance, all-in-one wireless solution designed to bridge the gap between traditional serial communication and modern Bluetooth connectivity. Engineered as a superior alternative to standard HC-05 and HC-06 modules, the XM-15B features an integrated power management chip and level conversion circuitry. This allows for direct, “plug-and-play” compatibility with both 3.3V and 5V systems—including Arduino, Raspberry Pi, and industrial PLCs—without the need for external voltage dividers or logic level shifters.
Whether you are developing a single prototype or integrating wireless data transfer into a large-scale industrial fleet, the XM-15B offers a “Universal” architecture. It supports Master, Slave, and Loopback modes, switchable via simple AT commands, making it flexible enough for any network role. Its robust design includes a hardware watchdog and anti-reverse power protection, ensuring system stability in demanding environments.
Key Features
- True 3.3V/5V Dual Compatibility: Built-in TTL signal level conversion allows seamless connection to 3V, 3.3V, or 5V microcontrollers.
- Master/Slave Versatility: Unlike slave-only modules, the XM-15B can initiate connections (Master) or wait for them (Slave), functioning as a complete replacement for both HC-05 and HC-06.
- Industrial-Grade Stability: Features an onboard hardware watchdog to prevent system crashes and a power management chip for stable operation between 3.0V and 6.0V.
- High-Speed Initialization: Completes full module and protocol stack initialization in just 0.3 seconds.
- Protection Circuitry: Integrated anti-reverse protection prevents module damage if the power supply is accidentally connected backward.
- Extended Range: Delivers a maximum transmit power of +10dB, offering reliable communication up to 30 meters in open conditions (up to 60m theoretical).
